Doctors as bystanders: Having a crowd of specialists on your case when you are hospitalized with a serious illness may not be such a good thing. Doctors trying to solve medical problems in groups are prone to the same sort of "bystander effect" that sometimes keeps people in crowds from helping crime victims, say doctors who describe such a case this week in the New England Journal of Medicine. They say no one took charge of the patient, who had multiple problems, until a crisis occurred 11 days into his hospitalization. (ABC News)

Unknown risk: One third of people getting CT scans did not know they were being exposed to radiation and just 1 in 20 knew that each scan slightly increases the lifetime risk of cancer, finds a survey from one medical center. While benefits often outweigh risks, more patients should know about the risks, doctors say. (Reuters)

The skin he is in: The man who was once the world's fattest has lost more than two-thirds of his former 980 pounds, but now has a super-sized version of a common problem: huge swaths of excess skin. Paul Mason of Ipswich, England, is awaiting approval for surgery to remove what doctors estimate is 75 pounds of flesh. (ABC News)

Today's talker: The late comedian Gilda Radner "would have cried" if she knew that some of the cancer support clubs named after her were changing their names, says Gene Wilder, her widower, in an interview published on Web2Carz, an automotive and lifestyle website. As the Huffington Post reports, several branches of Gilda's Club remain under her name, but others have rebranded themselves because they say young clients don't know who Radner was.
